What is AtomicInteger in Java?
AtomicInteger is a class in Java that provides an integer value that may be updated atomically. It is part of the java.util.concurrent package.
How does AtomicInteger differ from a regular integer?
Unlike a regular integer, AtomicInteger supports atomic operations, meaning it can be safely used in concurrent programming without explicit synchronization.
Can you give me an example of how to use AtomicInteger?
Sure! You can create an AtomicInteger like this: AtomicInteger atomicInt = new AtomicInteger(0);
Then, you can use methods like incrementAndGet()
to atomically increment its value.
What are some common use cases for AtomicInteger?
